2 theories I have, I am probably way off with both but I wonder...
1. Some refs don't like making a decision that will decide the meeting, so giving us a 5-1 means H15 decides it.
2. The ref realised they totally made a mess of H8 and as everyone went across together gave it to us to even it out?
As I said I am probably way off with these thoughts, but did cross my mind!
